Up for sale is a cocker threaded .688 Gloss black barrel back. (say that 3 times fast
I live in central MA, I will consider local exchanges.
As far as trades of interest go, I'd really like Arma II: Combined Ops on steam so I can play the DayZ mod, but you'd have to also add some $$ via paypal (cause this barrel isn't worth $25)
If you want to buy it, i'll say $40 obo. It's in great condition with only some wear from being screwed into the gun.
Thanks for looking!
